CPU utilization on DL580

Hi,

I am using OEL 5.3 64-bit on HP DL580 (4 CPU). i am decompressing the Oracle backup by tar command.

only one core is being utilized 65% and rest of the cores are free and load average is 4.4.

I want to know why the CPU is not being equally utilized?

Re: CPU utilization on DL580

Because gunzip isn't multithreaded. And I assume the gzip format doesn't lend itself to parallel processing.

Do something else with those CPUs.
